Check out this cool (and pointless) iPhone lock screen trick in iOS 7

There are plenty of useful iOS guides out there featuring extensive lists of tips and tricks. But what about iOS tips that are completely pointless? You know, the type of iOS tips will do nothing to increase your productivity or efficiency, but rather exist solely as something to show off to friends if you happen to find yourself bored at a party.

Well search no longer, friends. We've got such a tip for you today.

Thanks to a Reddit thread which surfaced last week, I stumbled upon a cool, and admittedly useless, iOS trick which at the very least shows off iOS 7's physics engine.

Here's how it all works.

From the iOS 7 lockscreen, there's a small camera icon located in the bottom right portion of the screen. As you may already know, you can quickly access the camera app by sliding the icon upwards.

But if you want to have a bit of fun, slide up the icon about three quarters of the way up and then slam (read: slide) it back down as fast as you can. If you do it right, you'll bounce the screen hard enough that it'll shoot all the way back up and open up the camera app in the process.
